Definitions

  • the invention relates to a system for playback programming of recording contributions and / or information stored on a recording medium.
  • a playback device e.g. a CD player which, among other things, stores the number, track number and jump address of an individual recording contribution after inserting the CD
  • an operating device assigned to the CD player e.g. Remote control to retrieve only the posts you want. To do this, either all desired track numbers of the desired recording contributions must be entered before the entire playback begins, or after playing a recording contribution, the track number of the next desired contribution must be entered.
  • DE-A-3842149 shows playback programming for a CD which has an optically scannable area with a start mark and with predetermined, manually markable locations. In each case, several markable places lying along a radius form a digital code for the position of a title on the disc. Programming is done on a label.
  • GB-A-2232805 shows the possibility that additionally applied line markings which describe the content of the record carrier can be read and evaluated by the CD player.
  • previous record carriers e.g. Compact disks, which have not yet had the features of the invention
  • the first object is achieved with a system for playback programming, which has the features of claim 1.
  • a system for playback programming which has the features of claim 1.
  • very advantageous configurations of individual features of the overall system are described.
  • a record carrier according to the invention is contained in claim 2.
  • the recording medium according to the invention is very easy to program, the value marking table on the recording medium is fixed and preferably inextricably linked to it, the programming or the assignment of a location in the area to a recording contribution or title is clear for everyone, especially since information is often on a recording medium anyway attached to the individual recording contributions.
  • the table with the record carrier forms an advantageous structural unit, so that programming can always apply unambiguously to only one record carrier and the corresponding record contributions and the programming itself can also be read by a user at any time.
  • the recording medium is preferably a CD or MOD (magneto-optical disk), photo CD or the like, which has a scanning side and a label side, the area being arranged in the form of the table on the label side or scanning side and each markable position being a jump address a recording contribution of the CD or MOD is assigned.
  • the jump address preferably represents the start address of a recording contribution.
  • the values for undesired recording contributions are preferably marked during playback programming (negative selection). It is also possible to achieve different control of playback parameters such as volume, sound, dynamics, etc. by means of different types of marking, such as, for example, line, bar, circle, alphanumeric markings, etc. at one point.
  • the markable area has additional markable points that are not assigned to a specific recording contribution. If one is marked, the volume or dynamics, for example, can be limited to a predetermined value when playing music signals.
  • the additional digits or additional marking types support individual playback programming of the recording contributions.
  • the markings of the locations in the area can preferably be deleted, so that simple reprogramming can be carried out. It is also expedient to adapt the number of possible markings or digits in the area of the number of titles on the recording medium.
  • a method for controlling a playback device with a recording device for a recording medium according to the invention is contained in claim 7.
  • the marked and / or unmarked values are displayed optically and / or acoustically on the playback device, so that after the user has placed the recording medium in or on the playback device, the user is constantly informed as to which recording contributions are played back in succession or according to a selection sequence.
  • the record carrier is circular like a CD, MOD or record
  • the table is scanned when the record carrier rotates.
  • the reading device for the scannable area can thus be arranged in a fixed manner in the reproducing device if the area is arranged on the label side.
  • the record carrier preferably has a constant rotational speed during the scanning process for the table.
  • the area should have marking locations or fields of the same size in order to ensure a reading process of the area that can be scanned that is as fail-safe as possible while the rotational speed remains the same.
  • the method can also be used very advantageously for controlling a playback device designed as an automatic changer device with a control system, the control system successively and / or selectively playing a large number of recording media, using a recording medium as described above and using a reading device in the changer or reproduction device, the reading device reading the local position of the marked and / or unmarked values and reading them into a memory in the changer device.
  • the playback of a first recording medium is started and the recording contributions assigned or desired to a value are reproduced.
  • the first record carrier is exchanged for a second record carrier when the desired record contributions have been played back by the first record carrier.
  • the process steps of starting and changing are repeated until all or a selection of several recording media has been played back.
  • EP 0224465 discloses a method for controlling an automatic changer device with a control system which enables the successive and / or selective playback of a large number of recording media, the user, however, entering a total number of the recording media to be played back once for all recording media. This method is inflexible, requires a considerable amount of circuitry in the changer device and is also very cumbersome and not individually programmable.
  • Claim 12 contains a playback device according to the invention for the system according to claim 1.
  • the separate reading device is preferably on the opposite side of the Optical scanner for scanning the audio and / or information is arranged in the CD player or MOD player.
  • reading or scanning the area on the label or scanning side is also possible with the audio scanner if the degree of reflection of the MOD or CD for light beams from the audio scanner is less than 100%, so that the light beams are the MOD or CD can penetrate.
  • the housing part of the playback device which is assigned to the label side of the MOD or CD, with a very bright or highly reflective surface in order to increase the contrast capability.
  • the values for them or the reference symbols assigned to the recording contributions such as e.g. Record contribution number, track number, title designation such as piece of music label, name of the artist, location and time of recording, etc. are shown on a display of the playback device.
  • 1 a shows the label side of a compact disc 1, on which a scannable table or area 2 is arranged, in which scannable markings at local predetermined fields or places 3 can be made selectively and manually.
  • the area forms an optically scannable code with the markings.
  • the first ten digits one to ten are each assigned a specific track number 17 on the CD. Positions eleven to twenty are vacant.
  • the area is printed on the label side of the CD or adheres to the CD as a special label 4.
  • the shape of the area or the label is a 1/3 circle of approximately 4 mm width for the marking positions with a numbering of the numbers one to twenty next to the fields 3 (FIGS. 1 a, 1 c) as an identifier assigned to the title numbers next to the positions .
  • Such an area or label may be too wide, so that the label on the outer edge on the label side of the CD can be covered when the label 4 is stuck on.
  • the area has only the width of the marking points, which in turn are numbered, so that the area is narrower than in FIGS. 1a and 1c.
  • the important information printed on the CD label page e.g. the table of contents 17, from which area 2 or the label are not covered and are therefore still accessible, in order to ensure easy assignment of the title and the markable area at any time, even without a booklet.
  • the outer edge of the CD on the label side is not filled with a label that is essential for the general understanding of the user, so that the scannable area can be accommodated there easily and very advantageously, because there the relatively largest space for the narrow area 2 is available.
  • the marks begin with a black and a white zone 5 and 6, which serve to synchronize a scanning circuit 7 (Fig. 2) in the reproducing device. This is followed by the twenty marking points 3 on which one does not want twenty You can mark music track 17 by coloring or filling in the relevant section in black.
  • the first position is assigned the first title 17.1, the second position the second title, etc.
  • the marking positions are followed by a black synchronization field 8a in the direction of rotation.
  • the CD has only ten music tracks, as in FIG. 1a, only the marking of tracks one to ten makes sense. It is therefore easier if the number of digits that can be marked on a CD corresponds exactly to the number of music tracks. In the case of a MOD, however, the number of digits should not be limited as much, since the number of contributions to the recording is usually still undetermined before a total MOD is recorded.
  • the white zone of the marking points 3 in the area 2 has a length of 5 ° (based on the center of the CD), which corresponds to a length of approximately 5 mm.
  • Appropriately adapted waiting loops for this length are present in the evaluation circuit or evaluation program of the microprocessor system (FIG. 2).
  • a region arrangement as described above is very advantageous for scanning with the rotational speed of the recording medium remaining approximately the same.
  • the most reliable function of the scanning circuit 7 was achieved with labels 4 made of white paper, the markings being made with a black felt pen. When marking, make sure that the contrast between the white and black areas is large enough. Under certain circumstances, a special felt pen with a special, infrared absorbing color is necessary, if as a reading device an infrared reflex light barrier is used for the markable points. When applying the label as well as when marking, it should be ensured that the sensitive label side of the CD is not damaged by scratches, plasticizers in the adhesive of the label or in the writing fluid of an marker pen.
  • pre-magnetized slices the size of a marking point. These are firmly attached to mark a point on the area and can be read with a magnetic scanner as a reading device in the CD player. There are no restrictions on the way of marking or inscribing the locations 3 in the area, as long as there is sufficient scannable contrast for the reading device 41 or 601.
  • area 2 is already pressed onto the reflective material during CD production, or the labels have a metallic reflective surface, the necessary contrast is easier to achieve. Then it may be sufficient if the individual marking fields 3 are marked with a well-covering contrast medium, preferably fast-drying paint.
  • a well-covering contrast medium preferably fast-drying paint.
  • the number of check boxes during production can be adapted to the number of tracks on the CD.
  • the markable fields (3) according to FIG. 1c each have a subdivision in area 2, for example in the middle or along the diagonals of a markable field.
  • a field is only marked up to half by the user if, in his opinion, this music title is reproduced, for example, disturbed by a scratch.
  • the scanning and recognition of different forms of marking is unproblematic for a reading device.
  • a countermeasure is then taken for the title marked in this way, ie the error correction circuit is sensitive from the outset to the occurrence of errors.
  • a CD 1 is regularly placed in a hinged hard box 51 (FIG. 5) and locked there in a holder 57 in a defined position.
  • the hard box is very well suited for the exact application of a label 52 according to FIG. 1c or 1d, if the label is a detachable part of a sheet 53, which is inserted in the left flap 54 in FIG. 5.
  • a booklet or information sheet with information about the CD releasably inserted between guides. Since the dimensions and dimensions of the CD are firmly defined in the hard box, a sheet in the left flap in FIG.
  • CD's and MOD's are arranged in a Cartrigde (fixed protective cover) and can also be played lying in the Cartrigde.
  • a slot on the scanning side is opened after the Cartrigde has been inserted, through which the laser scanner has access to the plate.
  • the Cartrigde on the label side in the section of the markings will also be made accessible if a separate marking scanner is used. This opening of the cartridge on the label side of the recording medium corresponds essentially to the size of a marking field.
  • the area is to be scanned by means of the laser scanner, it makes sense to provide the inside of the Cartrigde facing the label very brightly or with a highly reflective layer in order to reflect light beams from the audio scanner in a suitable manner or for the light beams to produce a correspondingly large contrast.
  • FIG. 2 shows a scanning circuit 7 with a microprocessor system in order to scan the marked locations 3 in the area 2 from the CD 1 and to process or evaluate the scanned values.
  • An infrared reflex light barrier of the MRL601 type is used as a fixed reading device for scanning the markings in area 3 from the CD 1. It consists of an infrared LED 8 and a photo transistor 9, which are integrated together in one housing. A built-in infrared filter ensures a high level of ambient light immunity, so that the circuit can be checked and set even when the device is open and with normal work lights. This is useful when hiring a prototype.
  • the light barrier MRL601 has a very good efficiency at a distance of 5 mm above the surface to be scanned and is therefore mounted at this height above the outer edge (circumference) of the CD 1 in the end position (play position) in the CD player.
  • the phototransistor is connected to the non-inverting input of a TAA861 operational amplifier, which amplifies pulses from the phototransistor.
  • a trim potentiometer 11 is set to the correct level and connected to the inverting input of the operational amplifier.
  • the setting can be easily carried out with the help of a two-channel oscilloscope, with which the pulses at the collector of the phototransistor are compared with those at the output of the operational amplifier.
  • the powerful pulses are reversed by a subsequent inverter 12, so that the bright areas in the area 2 cause positive pulses.
  • FIG. 4 An overall block diagram of a CD player 18 is shown in FIG. 4.
  • the microprocessor system shown as a data processing unit in FIG. 2 is integrated in the actual processor of the CD player, which processes the scanning signals from the reading device 601.
  • FIG. 2 The processing or evaluation (FIG. 2) of the pulses from the inverter 12 and the further control is carried out by the microprocessor system shown in FIG. 2, the heart of which is a Z-80 CPU processor.
  • the entire circuit (apart from EPROM 2764) is completely built in CMOS technology. The power consumption is so low that the supply voltage can be taken directly from the CD player.
  • Two further pieces of information are obtained from the CD player: an IC is tapped from an IC (not shown) that is responsible for the movement of the slide, on which the CD is drawn into the device, from the microprocessor a RESET Receives signal.
  • the microprocessor also receives a RESET signal when the CD player is switched on.
  • the scanning circuit therefore begins to work automatically as soon as the CD player is switched on or when a new CD is inserted through the carriage.
  • Another IC that drives the motor that rotates the CD taps pulses that indicate the motor's acceleration. If these impulses fail to appear, this is a sign that the CD is rotating at a constant speed. Only then are the markings of the positions evaluated. This happens right at the beginning when the CD player analyzes the inserted or inserted CD and determines, among other things, the number of tracks and the playing time. For this purpose, a fixed, unchangeable data directory - called TOC (Table Of Content) - and the UTOC (User Table Of Content) of the CD are read.
  • TOC Table Of Content
  • UTOC User Table Of Content
  • the information After analyzing the markings, the information must be passed on to the CD player. This is done by the microprocessor Z-80 simulating the corresponding control pulses from an infrared remote control. Therefore, the original connection between the infrared sensor 14 and the CD control IC is broken. Before this, the microprocessor switches off the infrared sensor of the CD player so that this simulation cannot be disturbed by a remote control. This state is made clear on the front of the device by the lighting of a light-emitting diode 13.
  • the Z-80 processor sends the signal for "programming", then the numbers of the unmarked tracks and then the signal for "play” to start music playback. Finally, the infrared transmitter is switched on again, whereupon the LED 13 goes out.
  • the programming system shown then changes to the halt state, which it can only leave by a renewed RESET signal. You can start playing the desired tracks. Incidentally, this halt state is assumed immediately if the system has determined in the absence of the black synchronization zone that the CD has no scannable area 2 or no markings in places 3.
  • the CD player now shows either the marked or unmarked track numbers on a display. Since the marked positions are assigned to the undesired titles as agreed, it makes sense to display the title numbers that are also reproduced, ie the numbers of the positions that are not marked with the exception of positions eleven - twenty.
  • the CD player now starts to play the tracks assigned to the unmarked positions one after the other. If, for example, the fields 1, 2, 5. 6, 7, 9 and 10 are marked as in FIG. 1a, the music pieces 3, 4 and 8 are reproduced automatically. After the CD has been inserted into the CD player, the third track is played automatically and without delay. The leap in time is also the same from track three to track eight roughly the same size as the jump from track three to four. The delay times when jumping from title four to eight are therefore very short.
  • the overall block diagram of a CD player 18 shown in FIG. 4 shows the reading device 601 facing the label side of the CD 1 and the scanning laser 41 facing the scanning side of the CD 1 in the CD recording device 19 in the CD player.
  • the reader 601 is controlled by a processor and the marked or unmarked values are read into a dynamic memory (RAM).
  • RAM dynamic memory
  • FIG. 3 shows a flow chart of a CD player designed as a CD changer device.
  • the changer device has a receiving device designed as a receiving compartment for a number n CD.
  • a control system permits the successive and / or selective playback of the recording media located in the receiving compartment.
  • a first CD is pulled over a sled into the play position. As described above, the area is scanned from the label side and the music tracks selected by the user are reproduced as described above.
  • the first CD is exchanged for a second CD stored in the recording compartment when the recording contributions assigned to the marked or unmarked positions have been played from the first CD.
